Clients and Patients come to us because they want something to change about their life. That change could be the removal of physical pain, dealing with emotional distress, changing their nutrition in order to lose weight, or decrease the effect of diagnosed disease on their overall quality of life.

Interestingly, one’s desire to change doesn’t always lead to change.

How can a practitioner from any discipline assist their client or patient to move from wanting to change to actually changing?

Motivational Interviewing (MI) is a communication strategy with a set of strategies ad tactics aspects designed to you, the practitioner, encourage the adoption of change behaviors.

Here is the most current definition:
“MI is a collaborative, goal-oriented style of communication with particular attention to the language of change. It is designed to strengthen personal motivation for and commitment to a specific goal by eliciting and exploring the person’s own reasons for change within an atmosphere of acceptance and compassion.”  (Miller & Rollnick, 2013, p. 29).

In this webinar, presenter Greg Mack will explore Motivational Interviewing and its practical application in real time interactions with clients or patients.

As Founder and CEO, Greg’s vision for Physicians Fitness  ( was shaped over 28 years ago while working as a lay assistant to physicians in a sports medicine clinic. It was during this tenure that he noticed the unfortunate reality that most of the patients of the clinic were there as a result of poor physical conditioning. He observed that the patient base consisted of individuals who would return to the clinic for treatment of re-injury to a problem area, or the development of new symptoms, due to compensation patterns created by the original pathophysiology. The medical and chiropractic staff encouraged these patients to participate in exercise and fitness programs, but did not have the time nor resources to effectively assess, develop, and implement a safe, global health-fitness plan. He is also a co-founder and partner in the Muscle System Consortia LLC, ( an education and research company dedicated creating and teaching a more mature and comprehensive understanding of the dynamic nature of skeletal muscle and its influence on the other body systems in order to appreciate its vital contribution to lifelong human health and performance, ultimately changing the world’s perspective on its care, use, and maintenance.

As a graduate of the US Navy’s Nuclear Engineering School with an emphasis in Mechanical Engineering and a qualified US Navy Diver, Greg used his foundation of engineering skills, his enthusiasm for fitness, academic certifications ACE- Personal Trainer (CPFT)ACEMedical Exercise Specialist (CMES)  (American Council on Exercise), and Resistance Training Specialist Mastery  ( – and his experiences working with a wide variety of medical professionals to develop the Muscle System Specialist ™ Training Program and the Mobility Profiling Method of pre-exercise physical assessment.

Greg has taught courses for several industry education companies on topics ranging from functional musculoskeletal anatomy, manual muscle testing, biomechanics, selling philosophy and methodology, physical assessment, decision-making, and science-based methodologies in exercise assessment and data interpretation. He has written articles published in IDEA Personal Trainer Magazine, American Fitness Quarterly, Body Conditioning Magazine, IDEA Health and Fitness Source Magazine, and The American Journal of Medicine and Sports.

His experience in working in such diverse venues as community gyms and medical practices enhanced his awareness of the wide gulf that exists between the medical community and fitness facilities particularly for those individuals trying to recover from and manage a diagnosed disease. This led to the development of a comprehensive documentation and communication system that coordinates fitness programs for individuals with diagnosed diseases from the medical community, the core of Physicians Fitness operations. This proven system of knowledge and practical skills is offered as a course through a subsidiary of Physicians Fitness – Exercise Professional Education ( and has been taught to exercise professionals from around the world.

He achieved the “Master Level” designation as a personal fitness professional from IDEA ( Greg received the IDEA International Personal Trainer of the Year Award for the year 2003 and was the Chairman of the IDEA Personal Trainer Committee, an influential body steering important issues related to fitness professionals.
